Melissa is a graduate student at George Mason University and holds a B.S. in physics from the University of South Alabama and an M.S. in physics from the University of Minnesota Duluth. While at UMD, Melissa focused on generating Post-Newtonian waveforms of coalescing binary black holes and producing animations of these orbits with its resulting gravitational waves. Her current research involves looking at the MIR spectroscopical properties of 200 AGN from the BASS Survey using the Spitzer telescope. The goal is to understand how the characteristics of the circumnuclear dust change with the accretion properties of the supermassive black hole. Melissa was awarded the Outstanding Graduate Teaching Assistant Award from the UMD Physics & Astronomy Department for the 2019-2020 academic year.

Jeffrey holds a B.S in applied physics and applied mathematics from Christopher Newport University. There his research focused on general relativity and black holes with a concentration on the creation of extragalactic jets. He also researched Compton scattering in the high field regime at Thomas Jefferson National Accelerator Facility in partnership with Old Dominion University. Jeffrey joined GMU to study Active Galactic Nuclei (AGN) from the X-ray perspective and is currently studying the effect of polar dust on X-ray spectra from AGNs using high resolution simulations. This polar dust was discovered after high resolution interferometry of AGNs in the mid-infrared found a large component extending in the polar direction, which is not expected by the classical unified model of AGNs. Studying this polar component of dust in the X-ray regime could act as a unique probe of the kinematics of the polar gas. These simulations will provide a fundamental benchmark for future high spectral resolution X-ray instruments, such as those onboard XRISM and Athena.
Ryan is a graduate student at George Mason University and holds a B.S. in Physics – with an emphasis in astrophysics – also from GMU. Utilizing X-ray observatories such as Chandra, XMM-Newton, and NuSTAR, his work focuses on the search for dual AGN in mid-IR preselected late-stage galaxy mergers, characterizing the levels of AGN obscuration in late-stage mergers, as well as understanding AGN triggering and fueling in mergers versus isolated galaxies. Ryan is the recipient of a several awards, including the Sigma Xi Grant-in-Aid of Research (GRIAR) and two competitive International Travel Grants (ITGs) offered by the GMU Associate Provost for Graduate Education. Outreach is also a very important activity for Ryan, and he regularly conducts class and public tours at the GMU observatory.

Her research interests are in the area of the evolution of galaxies and in particular, on the role that galaxy mergers play in the morphological transformation of galaxies, most recently concerning the structure of the nuclear regions of gas-rich galaxy mergers and in particular on the discovery of massive molecular outflows in gas-rich galaxy mergers and the implications for understanding galaxy feedback in these systems.
Dr. Gliozzi’s research activity is focused on the investigation of the physical conditions of matter around black holes based on the analysis and interpretation of X-ray data from different classes of active galactic nuclei (AGN; especially Radio Galaxies, Blazars, Narrow Line Seyfert 1 galaxies, and true type 2 AGN). He is interested in the unification of black hole systems at three different levels:
1) The unification among the different classes of AGN, with particular focus on the radio-loud/radio quiet dichotomy
2) The unification between active and normal galaxies, investigated by studying the X-ray nuclear properties of bulgeless galaxies and Low-power AGN, which may represent the link between powerful AGN and normal galaxies.
3) The unification between AGN and Galactic Black Hole systems, with particular emphasis for the variability properties .

Barry Rothberg obtained his Ph.D. from the University of Hawaii at Manoa in 2004. His Ph.D. dissertation focused on using near-infrared imaging and optical spectroscopy to study the dynamics of merging galaxies in the local Universe. In 2005, he joined Space Telescope Science Institute as a postdoctoral fellow to work on young star clusters in merging galaxies, and in 2007, he was awarded a National Research Council Fellowship at the Naval Research Laboratory where he worked with Dr. Jacqueline Fischer to unravel why some galaxies appeared to have dramatically different masses depending on the wavelength of light used to observe them. In 2011, Dr. Rothberg rejoined Space Telescope to provide support for the slitless grism mode on the the Wide Field Camera 3 aboard the Hubble Telescope. In 2012, he joined the Leibniz Institute for Astrophysics (AIP) as a Senior Postdoctoral Fellow and Support Astronomer for the institute’s share of the Large Binocular Telescope located on Mount Graham in Arizona. Dr. Rothberg continues to work on the properties of merging galaxies in the local Universe and has expanded this work to investigate similar systems at earlier epochs (as far back as 8 Billion lightyears). He is also working with Dr. Pirzkal at Space Telescope Science Institute to apply more robust statistical methods to detecting and measuring the properties of galaxies formed within a few hundred million years after the Big Bang. Dr. Rothberg is currently working to study the properties of black holes in bulgeless and low mass galaxies, as well as merger-triggered accretion onto black holes.
